SAFE TY ATTACHMENT-FOR BOX-MACHINES.

SPEGIFIGATION forming part of Letters Patent No. 536,044, dated March19, 1895.

Application filed August 24,189 Serial No. 521,223. on, model.)

To all whom it may concern:

Be it known that I, ABRAM A. RHEUTAN, a citizen of the United States,residing at Worcester, in the county of Worcester and 5 State ofMassachusetts, have invented a new and useful Improvement in SafetyAttachments for Box-Machines, of which the following is a specification.

My invention relates to that class of ma- 1o chines, which are used forforming the ends of paper boxes, or end-setting or ending, as it istechnically called in this art, and the especial object of my inventionis to provide machines of this class with safety attachments r5 orguards for the hands of the operator.

To this end, my invention consists of the parts and arrangement of partsas hereinafter described and more particularly pointed out in the claimsat the end of this specification.

part of this specification, Figure l is a perspective View of a portionof. an end-setting box machine showing my safety attachment or guardapplied thereto. Fig.2 is an end view of the form with the safetyattachment applied thereto, the position of the work and of theoperators hands being indicated. Fig. 3 is a bottom plan view of mysafety attachment or guard removed from the machine. Referring to thedrawings and in detail, A, A designate the side frames of the machine,which are provided with vertical guide-ways O, C, in which is mounted areciprocating plate B, which is adapted to be moved up and 5 down bymeans of suitable pitmen as indicated at D, the said pitmen beingconnected to and actuated from the driving mechanism of the machine.

Near its center, the reciprocating plate B is provided with a projectionor bracket E, the form F being detachably secured to said bracket asshown.

In operating machines of this class, the blank or partially formed boxis placed by the operator upon the form F and the inachine is operatedto raise'the plate B until the form F is brought into contact with theplaten G. The platen G is held down by springs Has shown, suitablesubsidiary devices being provided for closing the .box in the well knownmanner. These parts may be of the ordinary In the accompanying drawings,forming or approved construction and need not be herein described atfurther length.

In practice, it has been found that machines of this class aredangerous, as the operator is apt to hold the box or blank onto thesides of the form until the form engages the platen, and if the operatordoes this his fingers are apt to slip over the top of the form, and tobe caught and injured between the form and the platen. To overcome thisdefect, I have provided safety attachments or guards I, which arearranged at each side of the form as shown. In the construction, which Ipreferably employ, the guard is formed integrally with a sprihg clip forholding the work in place and by means of this construction, it will beseen that I have provided a guard plate or projection which will preventthe fingers of. the operator from rising above the reciprocating form,while at the same time this guard or projection will not interfere withthe work, which may be freely inserted between the spring clip and theside of the form and may be extended above the upper surface of the formin a position to be properly acted upon.

As illustrated in Fig. 3, 1O designates a strip of spring sheet metal,which is bent as at 11 and is secured to the rear end of the form by oneor more screws 12. The spring strip 10 is bent as shown as at 13 and isprovided with a portion 14, which comes in contact with the side of theform F and aids in holding the work in place. Extending laterally fromthe spring clip 10 and preferably formed integrally therewith, I providethe guard plate 15. As the operator places the work on the form belowthe said plate, the plate will prevent his fingers from extending upover the form in a position to be caught between the form and theplaten. By the use of such an attachment, machines of this class will berendered much safer and more rapid in operation.

Instead of having the guard plate formed integrally with the spring clip10, I may form the guard plate from a separate piece of metal and I maysolder or secure the said guard plate to the spring clip in any desiredmanner.

I am aware'that other changes may be made in the construction of mysafety attachment for end setting box-machines, by those who are skilledin the art, therefore, I do not wish to be limited to the details ofconstruction,

which I have shown and described, but

What I do claim, and desire to secure by Letters Patent of the UnitedStates, is-

1. In an end setting box machine, the com for1n,and a guard plate orprojection extending laterally from each of said spring clips,substantially as described.

4. In an end setting box-machine, the combination of a reciprocatingform and spring clips secured to the rear face of said form, said clipsbeing bent around to engage the work upon the side faces of said formand having integral, laterally extending guard plates or projections,substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

ABRAM A. RHEUTAN.
